Applying this principle systematically allows us to expand the given product, transforming it from a compact form into a more detailed expression. From there, we can identify and combine like terms, streamlining the result into its simplest and most manageable form. The ultimate goal is not just to arrive at the correct answer but to grasp the underlying logic and methodology, empowering you to tackle similar problems with confidence and skill. So, let's embark on this mathematical adventure, unlocking the secrets hidden within the product of these polynomial expressions.
Mastering the art of polynomial multiplication opens doors to more advanced mathematical concepts. It is a building block for calculus, linear algebra, and various other branches of mathematics. The ability to manipulate algebraic expressions efficiently is not only valuable in academic settings but also in many professional fields, including engineering, computer science, and finance. As we delve deeper into the expansion and simplification of (-2d^2 + s)(5d^2 - 6s), remember that each step is a learning opportunity, a chance to solidify your understanding and hone your mathematical prowess. The journey may seem intricate at times, but the rewards of mastering these skills are well worth the effort. So, let's proceed with curiosity and determination, unraveling the intricacies of polynomial multiplication and expanding our mathematical horizons.
Step-by-Step Expansion of (-2d^2 + s)(5d^2 - 6s)
To begin, we apply the distributive property, also known as the FOIL (First, Outer, Inner, Last) method, to expand the product. This involves multiplying each term in the first expression by each term in the second expression. Let's break it down:
- First: Multiply the first terms in each parenthesis: (-2d^2) * (5d^2) = -10d^4
- Outer: Multiply the outer terms: (-2d^2) * (-6s) = 12d^2s
- Inner: Multiply the inner terms: (s) * (5d^2) = 5d^2s
- Last: Multiply the last terms: (s) * (-6s) = -6s^2
Combining these results, we get:
-10d^4 + 12d^2s + 5d^2s - 6s^2
This expanded form now presents an opportunity to simplify the expression further by combining like terms. Like terms are those that have the same variables raised to the same powers. In this case, the terms 12d^2s and 5d^2s are like terms because they both contain the variables d and s raised to the powers of 2 and 1, respectively. Combining these terms is a crucial step in simplifying the expression to its most concise form. This process not only makes the expression easier to read and understand but also facilitates further mathematical operations involving the expression.
The ability to identify and combine like terms is a fundamental skill in algebra. It allows us to reduce complex expressions to their simplest forms, making them easier to work with in various mathematical contexts. In this particular example, combining the like terms 12d^2s and 5d^2s involves adding their coefficients, which are 12 and 5, respectively. This addition results in a new coefficient of 17, leading to the combined term 17d^2s. This step is a clear demonstration of how algebraic simplification can transform an expression into a more manageable form. By carefully applying the rules of algebra, we can navigate through complex expressions and arrive at elegant and concise solutions. This process not only enhances our understanding of mathematical concepts but also builds confidence in our ability to tackle more challenging problems.
Simplifying algebraic expressions is not just a matter of mathematical manipulation; it is also an exercise in logical thinking and problem-solving. Each step in the process requires careful attention to detail and a clear understanding of the underlying principles. The combination of like terms, as demonstrated in this example, is a prime illustration of this. By systematically identifying and combining terms with the same variables and exponents, we can effectively reduce the complexity of an expression. This skill is not only essential in algebra but also in other branches of mathematics and in various real-world applications. The ability to simplify expressions allows us to model and solve problems more efficiently, making it a valuable asset in any quantitative field. So, let's continue to hone our algebraic skills, embracing the challenges and rewards that come with mastering mathematical concepts.
Simplifying by Combining Like Terms
Now, let's combine the like terms 12d^2s and 5d^2s:
12d^2s + 5d^2s = 17d^2s
Substituting this back into the expression, we get:
-10d^4 + 17d^2s - 6s^2
This is the simplified form of the original expression. There are no more like terms to combine, and the expression is now in its most concise form. This final form reveals the underlying structure of the product, showcasing the relationship between the variables d and s and their respective coefficients. The process of simplification not only makes the expression easier to read and understand but also provides valuable insights into its mathematical properties. This skill is essential for solving equations, graphing functions, and performing other algebraic manipulations.
The journey from the initial product (-2d^2 + s)(5d^2 - 6s) to the simplified form -10d^4 + 17d^2s - 6s^2 highlights the power of algebraic manipulation. Each step in the process, from applying the distributive property to combining like terms, contributes to a clearer and more manageable expression. This final form is not only aesthetically pleasing but also more practical for various mathematical applications. It allows us to easily identify the terms, their coefficients, and the relationship between the variables. This level of clarity is crucial for solving equations, graphing functions, and modeling real-world phenomena. The ability to simplify algebraic expressions is a cornerstone of mathematical proficiency, enabling us to tackle complex problems with confidence and precision.
